How to identify Labradorite

Gray body with blue, green, gold, or multicolor labradorescence that moves as the stone turns. Finnish Spectrolite is noted for especially vivid full-spectrum color.

Lookalikes

Commonly confused with

Larvikite, moonstone, coated glass, and backed cabochons.

Market context

Treatments and imitations

Coating, backing, filling, and assembly can intensify flash.

Observation guide

What to check

Rock the stone under one light; internal flash changes with angle. Inspect edges for films and glue. Flash color cannot establish locality.

Use visual checks to ask better questions, not to replace qualified testing when identity, treatment, value, or origin is consequential.

Practical handling

Care and safety

No steam or ultrasonic cleaning. Protect cleavage edges and use mild soap.

Responsible buying

Ethics and sourcing

Use Spectrolite specifically for documented Finnish material. Canadian, Finnish, and Madagascar claims all require records.

The material story

A short story about Labradorite

Named for Labrador, Canada; Spectrolite was discovered at Ylämaa, Finland, while Madagascar is a major source of commercial carving rough.
